Actually, a folkboat is a lot better than 300 prhf. In fact, if you look into it, you will find they are a lot quicker than you think.
"20 small boats to take you anywhere" lists the folkboat as having a rating as follows:
international 26ft folkboat without inboard
propeller: 234 (easy to remember no?)
with a
propeller, it states she comes in at 242.
There you are.
A 300 rating may be for a 25 foot (original folkboat) with a prop, still, I think it is a lot faster than that.
Cheers,
Mick.
